sysvinit - Remove sulogin dependency on /usr/lib*/libcrypt.a

The sulogin compile checked for /usr/lib*/libcrypt.a to decide whether
to add -lcrypt to the final compile.  However, the recipe puts LCRYPT
in the environment, so crypt-lib.patch makes the Makefile check for
this before looking at the host /usr/lib.
